Olives in the Mountains
Olives have been grown in the Mediterranean region for millennia and have been a staple crop in many of its cultures. This was never more true than during the Hellenistic (323 – 133 BC) and Roman (133 BC – AD 450) periods in the Mediterranean. This thesis examines the territory of the Roman city of Sagalassos in the region of Pisidia, modern province of Burdur, and determines if olives could have been cultivated in the territory. While there have been studies that state olives were cultivated in the territory during the Hellenistic and Roman periods, modern farmers as well as agronomic manuals state that such growth is not possible. This thesis present data that indicates that olives were grown in the territory of Sagalassos, but also examines the conditions olives require to grow and if such conditions existed in Pisidia. Through this I will be able to conclude whether the past presentation of data has does indeed prove that olives were grown within the territory of Sagalassos.

Hibernian Imagination
Artistic expressions such as writing, theatrical productions, music, and film arguably contribute to a culture’s representation of itself to the outside world. Most cultures have been either read or misread through their artistic outputs over the course of history, although the Irish culture stands as a particularly misunderstood one. Through years of colonization and rebel warfare, the country’s culture has acquired a particularly imagined depiction; violent, which through centuries has resulted in a flawed cultural imaginary today. This thesis presents this issue and proposes a means to better understand the Irish culture through a deeper understanding of the factors that have led the country’s cultural imaginary to its current misrepresentative state. Through an exploration of texts, theatre, music, and film, this thesis uncovers the factors which have led to Ireland’s current cultural depiction in hopes of creating a better understanding of the Irish culture.

Anti-Social Cognition
Callousness, deceit, and manipulativeness have been identified as common characteristics of the Dark Triad. Researchers have argued that empathy and Theory of Mind underlie these characteristics. This study aimed to (a) examine the relationships between the Dark Triad, empathy, and Theory of Mind, (b) determine if empathy and Theory of Mind explain the overlap between the Dark Triad personalities, and (c) test if Theory of Mind mediated the relationship between cognitive empathy and the Dark Triad. A sample of 267 undergraduate students completed self-report scales and a film-based assessment to measure the variables of interest. The results indicated that the Dark Triad personalities were negatively associated with affective empathy but were not uniformly associated with cognitive empathy and Theory of Mind. Affective empathy did not explain the overlap between the Dark Triad personalities. Finally, Theory of Mind did not mediate the relationship between cognitive empathy and the Dark Triad. Author Keywords: Dark Triad, Empathy, Mediation, Theory of Mind
Developing social skills
Guidelines regarding social skills interventions for children with ASD suggest incorporating a holistic approach. This includes increasing the family’s understanding of deficits associated with ASD, integrations of natural environments, and parents as active agents while supporting their well-being. The current availability of holistic parent-mediated interventions for children with ASD is limited, with no qualitative understanding of its potential benefits for either the parent or child. The current study examined qualitative parent reports on a parent-mediated social skills intervention for children with ASD (TalkAbilityTM) incorporating a longitudinal approach (i.e., 6-month follow-up). Following Braun and Clarke’s model of thematic analysis, data was coded into four themes: 1) communication difficulties, frustrations and progress, 2) social relationships and concerns, 3) communication strategies, and 4) thoughts and emotions surrounding TalkAbilityTM. Results highlight the importance of considering parent experiences regarding interventions for their child’s social communication skills through a qualitative viewpoint. Author Keywords: autism spectrum disorder, parent-mediated intervention, qualitative review
Temporal Variability of Coloured Dissolved Organic Matter in the Canada Basin, Arctic Ocean (2007-2017)
This thesis investigated coloured and fluorescent dissolved organic matter in the Canada Basin, Arctic Ocean from 2007 to 2017. The first interannual time-series of its kind in the Canada Basin incorporated the use of EEM-PARAFAC to validate a seven-component model. Statistical temporal tests revealed (1) an increasing protein-like intensity in the upper polar mixed layer (UPML); (2) increasing intensities of humic-like components in the halocline due to increasing freshwater content; and (3) no change in DOM composition in deeper Atlantic waters (AW) congruent with the long residence time of the water mass (> 30 years). The significant decline in sea ice concentration was related to a decrease in humic-like FDOM due to enhanced photodegradation and an increase in protein-like FDOM, likely the results of increased biological activities in surface layers. This research provides evidence that the changes in physical and biological environment in the Arctic regions have already profound impacts on the composition and distribution of FDOM.

An Exploration of Attachment Influences on Rape Attitudes
While there is substantial research on the influence of adverse childhood experiences on sexual offending behaviours and attachment representations on sexual offending behaviours, few studies to date have explored how adverse childhood experiences and attachment representations act together to influence the development of rape attitudes in a non-clinical population. The purpose of this thesis was to explore how childhood experiences and attachment may help to understand the development of rape attitudes. Data were collected from 273 undergraduate students who completed self-report questionnaires pertaining to their attachment, childhood experiences and rape attitudes. Correlational and Structural Equation analyses were computed, and the results did not find support for the simultaneous influence of adverse childhood experiences and attachment representations on rape attitudes. Given that the sample was primarily female (83%), the results indicate that the outcomes of adverse childhood experiences on sexual attitudes may differ by gender. Understanding the formation of rape attitudes is important to understand the motivations behind sexual assault behaviours. Author Keywords: adverse childhood experiences, rape attitudes
An Official Plan for Peterborough, Ontario
Using the Official Plan as the case study, this research examines the extent to which underrepresented groups are engaged in public consultation in the planning process for the City of Peterborough, Ontario, Canada. The Official Plan, along with the tools and secondary plans and policies which reinforce it, shape how people navigate and benefit from the built environment, such as access to public institutions and amenities, transit, parks, safe public space, quality housing, and more. This research frames the Official Plan as an opportunity for the city to demonstrate its new commitment to transparency and community engagement. Drawing on a range of experts and community members, and best engagement practices of other Canadian municipalities and nongovernmental organizations, a set of recommendations is proposed for the city’s community engagement framework. These recommendations emphasize an inclusive, democratic, and feminist approach to engagement and consultation which honours lived experience and local knowledge of diverse and underrepresented demographics and multi-sector stakeholders. Author Keywords: diversity, equity , inclusion, marginalized , public engagement, underrepresented
Understanding Angler Dynamics in a Recreational Lake Trout (Salvelinus namaycush) Fishery in Algonquin Provincial Park Using Long-Term Access Creel Data
In order to effectively manage recreational fisheries, it is important to understand how the resource is being used. In this thesis, long-term creel census data, collected on Lake Opeongo in Algonquin Provincial Park, Ontario, Canada was used to assess fine-scale angler dynamics within a recreational Lake Trout (Salvelinus namaycush) fishery. The spatial distribution of angler reported catch locations of Lake Trout within the lake, was assessed using an Optimized Hotspot Analysis in ArcGIS. Areas of significant clustering of catch locations were revealed during all time periods and varied in size and location both seasonally and temporally. Cormack-Jolly-Seber models were used to evaluate the probability of individual angling boats persisting in the regional fishery and being detected on Lake Opeongo through time, as well as to examine the effect of angler travel distance and gas prices on participation parameters. Time-varying models revealed that the probability of an angler persisting in the fishery varied, while detection estimates remained stable. Travel distance had a negative effect on both parameters while increased gas prices only had a slight negative effect on detection estimates. Additionally, among Lake Opeongo anglers, angling avidity varied as did lake specific fishing experience. Average CUE was found to be higher among angling parties who visited the lake more often than fishing parties who visited relatively few times. Author Keywords:
Examining the Role of Intermediary Organizations in Participatory Planning
This research evaluates the role of GreenUP, a non-profit in Peterborough, Ontario, as the intermediary organization for NeighbourPLAN. The project examines GreenUP’s role in facilitating and managing NeighbourPLAN, a participatory planning project with multiple local partners and actors. Six critical success factors are used to understand and conceptualize intermediary success (adapted from Holden et al., 2016). Critical success factors include knowledge; governance; relationships; resources; activities; and motivation. Findings from the research highlight the importance of trust, resources, and time within this framework.

An Analysis of Hafted Biface Variability in the Kawartha Lakes and Trent River Drainage Region
The objective of this thesis is to evaluate the temporal sensitivity of morphological variability in hafted bifaces in the Kawartha Lakes and Trent River drainage region. This provides a base of information that will enable future analyses that address the possible sources of this variability and to test the robustness of existing typological categories of hafted bifaces for relative dating. This base of information is established via the use of a principal component analysis of shape, raw material, and use-life data from a large sample of hafted bifaces in the region, using a new geometric morphometrics method designed to improve the accuracy of shape representation. The results of the analysis indicate that while certain typological categories may represent distinct morphotypes that are temporally sensitive, the majority of typological categories in the sample show high, overlapping morphological variability that cannot be confidently correlated temporally based on shape alone.

North Shore Legacies
On the North Shore of Lake Ontario near Port Hope, Ontario is a large archaeological site (BaGo-29) that has been visited and occupied multiple times over the millennia. First called the Beatty site was originally excavated by avocational archaeologist Mr. Ed. Austin between 1963 and 1972. In the subsequent decades, the Beatty site would be revisited, renamed the Gibbs site, and re-excavated without knowledge of Mr. Austin’s initial investigations of the site. The present research concerns the study of the E.W. Austin Beatty site legacy collection. Inter-site comparisons of the E.W. Austin Beatty site assemblage to others throughout Southern Ontario and upstate New York in combination with intra-site analysis of the material culture remains and chronologically significant variables contained in the Austin assemblage reveal that the occupational history of the Beatty site may not be as simple as subsequent excavations have interpreted.

collaborative ecotoxicological risk assessment of in-place pollutants in Owen Sound Bay, Lake Huron within the Saugeen Ojibway Nation Territory
Owen Sound Bay, which is located within the traditional territory of the Saugeen Ojibway Nation (SON), is contaminated as a result of historical industrial and shipping activity. Gross contamination of the sediments in the inner part of the Bay (i.e., Owen Sound Harbour) includes high concentrations of polycyclic aromatic hydrocarbons (PAHs) and other organic compounds, as well as metals that may pose a risk to the SON fishery for lake whitefish (Coregonus clupeaformis). However, evaluating the environmental risks posed by contaminated sediments is a challenge, as these risks are dependent upon several factors and require multiple lines of evidence. Including Indigenous communities in environmental risk assessment and the management of those risks is vital for sustaining ecosystem integrity, as well as respecting Treaty Rights. In this study, a risk assessment framework was developed that included several risk assessment tools used in Western science and also encompassed the concerns and values of the SON, including the application of SON-ecological knowledge. Methods for risk evaluation included gathering lines of evidence though community workshops, as well as field sampling in the Bay to determine the concentrations of PAHs and other organic contaminants in sediments and in the water column. Laboratory studies of toxicity to early life stages of lake whitefish and Japanese medaka (Oryzias latipes) and sediment disturbance simulations to evaluate biological responses in juvenile lake whitefish were also completed as lines of evidence. The results indicate that leaving the harbour “as is” without a thorough analysis of remediation options fails to address the concerns of the people within the SON communities. Overall, this research demonstrated a successful process for developing a collaborative risk assessment framework that recognizes the sovereignty of Indigenous peoples and promotes Nation-to-Nation decision making. Author Keywords: biomarkers, Coregonus clupeaformis, Indigenous knowledge, polycyclic aromatic hydrocarbons, risk assessment, source tracking
